This part of the article implies that permits are needed....
With the new laws, the state created a system of fines for rain catchers without a permit; previously the only option was to shut a collector down.
But Kevin Rein, Colorado’s assistant state engineer, said enforcement would focus on people who violated water rules on a large scale.
“It’s not going to be a situation where we’re sending out people to look in backyards,” Mr. Rein said.
Is this akin to purchasing a fishing license, drivers license etc???
I couldn't find it mentioned clearly in the article, maybe someone from Colorado can provide some details of the new laws on rainwater collection..
